One of the greatest mysteries of the Amazon rainforest is the Amazonian dark earth.
Unlike the surrounding poor tropical soil, Amazonian dark earth is a fertile black soil found across around 3-4% of the Amazon rainforest.
This soil contains fragments of charcoal, pottery, bones, & other organic material.
The Amazon has long been thought of as pure wilderness with only a scattered population of indigenous people.
However, the extent of this soil shows that a great deal of human effort went into making infertile soil fertile.
The changes made to the soil are still the subject of research & hold lessons for modern soil management.
Perhaps the Amazon was once home to a much larger population than we ever thought.
The Amazon is not entirely natural; it has been modified by human activity to a significant extent. People planted desired trees, modified soils, & changed landscapes.
The dense canopy of the Amazon holds the mystery of a lost civilisation. There are still many answers hidden in the dark, green shade of the Amazon canopy.
